Role of Part 3086273 Lubricating Oil Suction Tube in Engine Systems

The lubricating oil suction tube, identified as part 3086273, is integral to the efficient operation of engine systems. This component is responsible for drawing oil from the oil pan and delivering it to the oil pump. The arrangement of the suction tube within the engine system ensures a consistent and reliable flow of oil, which is essential for maintaining proper lubrication of moving parts.

The oil pan serves as the reservoir for the engine’s lubrication system. It collects and stores the oil that circulates through the engine, ensuring that there is always a sufficient supply available for the suction tube to draw from. The design of the oil pan, including its capacity and the placement of the suction tube, plays a significant role in the effectiveness of the lubrication system.

As the suction tube draws oil from the pan, it must be positioned correctly to avoid aeration and ensure a steady stream of oil reaches the pump. The oil, once drawn up by the suction tube, is then pressurized by the oil pump and distributed throughout the engine to lubricate critical components such as bearings, pistons, and camshafts.

The efficiency of the lubrication system depends on the seamless interaction between the oil pan, the suction tube, and the oil pump. Proper maintenance and inspection of these components are necessary to ensure that the engine operates smoothly and efficiently, with minimal wear on its internal parts.

Conclusion

The Lubricating Oil Suction Tube (part #3086273) by Cummins is a critical component in the engine lubrication system, ensuring efficient oil circulation and maintaining engine performance and longevity.
